If you're a Campusfish subscriber, try sending a picture message from your phone to email@example.com, replacing username and password with, well, you know. I think they're case sensitive, so in my case I have to use "Jeff" and not "jeff" in the e-mail address.
So far I know it works with Verizon, which is my provider. So if you're "in," don't bother because I know yours works. :)
Edit: I know there's a problem with Cingular. Actually, it's a problem with the e-mail component I'm using... but I working with the programmer to work it out. I mean, I think he wants my business.
